【摘要】 运用了Ｕｓｄｐｆ（１６）相互作用玻色子模型讨论了八极自由度Ｐ和ｆ玻色子对转动区偶偶核正宇称态的效应．结果表明，偶数个Ｐ和ｆ玻色子的组态能够混入到通常的基态带，β和γ振动带，并且自然地形成Ｋπ＝１＋、３＋等转动带．这一结果与Ｕｓｄｇ（１５）－ＩＢＭ相类似．本文还简要地给出了基态带间的Ｅ２约化跃迁几率，其结果与Ｕｓｄ（６）－ＩＢＭ相一致．更多还原

【Abstract】 Within the framework of the Usdpf (16) interacting boson model, effects of theoctupole degree of freedom p-and f-bosons on the positive-parity states of even-evennuclei in rotational regions are discussed. It is shown that configurations of an evennumber of p-and f-bosons not only can be incorporated into the usual ground stateband, β- .γ-vibrational bands, but also naturally form the Kπ=1+.3+ rotational bandsetc. This result is similar to that of the Usdg (15)-IBM. Besides, E2 transition probabilities are discussed briefly.更多还原
